R.J. Sommers
The single-spaced paragraph on the “About the Author” page of R.J. Sommers’ latest novel says she lives in a one-story house on the edge of a city. It says she is renowned for writing relatable characters and compelling relationships. It says nothing about her own friends.
Gazing from a photo at the top of the page, R.J. Sommers appears to point a camera toward her readers..
Heavy ion collisions in the used nucleon model
It is shown that recently proposed by R.J. Glauber the used nucleon model
combined with the assumption that the nucleon consists of two constituents (a
quark and a diquark) describes well the PHOBOS data on particle production at
midrapidity.Comment: 5 pages, 2 figure

On Hamiltonicity of {claw, net}-free graphs
An st-path is a path with the end-vertices s and t. An s-path is a path with
an end-vertex s. The results of this paper include necessary and sufficient
conditions for a {claw, net}-free graph G with given two different vertices s,
t and an edge e to have (1)a Hamiltonian s-path, (2) a Hamiltonian st-path, (3)
a Hamiltonian s- and st-paths containing edge e when G has connectivity one,
and (4) a Hamiltonian cycle containing e when G is 2-connected. These results
imply that a connected {claw, net}-free graph has a Hamiltonian path and a
2-connected {claw, net}-free graph has a Hamiltonian cycle [D. Duffus, R.J.
Gould, M.S. Jacobson, Forbidden Subgraphs and the Hamiltonian Theme, in The
Theory and Application of Graphs (Kalamazoo, Mich., 1980$), Wiley, New York
(1981) 297--316.] Our proofs of (1)-(4) are shorter than the proofs of their
corollaries in [D. Duffus, R.J. Gould, M.S. Jacobson] and provide
polynomial-time algorithms for solving the corresponding Hamiltonicity
problems.
